nvim-tree window moves to the right after opening a new file

[senicko]

Description

After entering neovim inside a directory and choosing a file, file explorer moves to the right (the file opens to the left of the file explorer). After reopening the nvim-tree window with :NvimTreeClose, :NvimTreeOpen everything works as expected.

I updated my plugins yesterday (I didn't update it for a few months), and I didn't have that issue before.

I am still experiencing the issue with only nvim-tree installed, so it is not caused by another plugin.

Is it because of recent config changes?

Neovim version

NVIM v0.6.1
Build type: Release
LuaJIT 2.1.0-beta3

Operating system and version

macOS 12.2.1

nvim-tree version

7b0ebf8

Steps to reproduce

Open neovim with nvim-tree installed inside a directory and open a file using nvim-tree.

Expected behavior

After opening neovim in directory and choosing a file it should open to the right of an explorer.

Actual behavior

The file opens on the left (nvim-tree moves to the right), but after reopening nvim-tree it works as expected.

Minimal config

vim.cmd [[set runtimepath=$VIMRUNTIME]]
vim.cmd [[set packpath=/tmp/nvt-min/site]]
local package_root = "/tmp/nvt-min/site/pack"
local install_path = package_root .. "/packer/start/packer.nvim"
local function load_plugins()
  require("packer").startup {
    {
      "wbthomason/packer.nvim",
      "kyazdani42/nvim-tree.lua",
      "kyazdani42/nvim-web-devicons",
      -- ADD PLUGINS THAT ARE _NECESSARY_ FOR REPRODUCING THE ISSUE
    },
    config = {
      package_root = package_root,
      compile_path = install_path .. "/plugin/packer_compiled.lua",
      display = { non_interactive = true },
    },
  }
end
if vim.fn.isdirectory(install_path) == 0 then
  print "Installing nvim-tree and dependencies."
  vim.fn.system { "git", "clone", "--depth=1", "https://github.com/wbthomason/packer.nvim", install_path }
end
load_plugins()
require("packer").sync()
vim.cmd [[autocmd User PackerComplete ++once echo "Ready!" | lua setup()]]
vim.opt.termguicolors = true
vim.opt.cursorline = true

-- MODIFY NVIM-TREE SETTINGS THAT ARE _NECESSARY_ FOR REPRODUCING THE ISSUE
_G.setup = function()
  require("nvim-tree").setup {
      auto_close = true,
      view = {
        side = "left",
        width = 30,
      },
      actions = {

        }
      }
  }
end

Hi!

I'm having the same problem but the other way around, I have nvim tree configured for the right side and on first open it opens on the left and after closing it and opening it again it opens on the right side.

I'm using LunarVim btw.

Hi, same problem here.

                { key = "v", cb = tree_cb("vsplit") },
            },
        },

Hi! Same here. Even with the default config.

[kyazdani42]

What is the output of :lua print(require"nvim-tree.view".View.side) ?

Oh, I didn't see this issue. Setting set splitright solves the problem. But as you said in https://github.com/kyazdani42/nvim-tree.lua/issues/1072 it is a global option. resize_window = true does not work on it own.

[kyazdani42]

indeed it does not. resize does not replace, i thought it did. Doesn't matter, i think this should be documented, i'll add a note in the readme. Closing since it's not an nvim-tree issue :)

[orangethewell]

I'm having the same problem too, resize_window = true doesn't work except if I close and re-open it

[xieping5555]

did you solve this problem?
